The Smithsonian’s amazing museums are instantly familiar to all of us, but their educational programming isn’t quite as popular. Though, now you can get it on iTunes for cheap. $1.99 for 45 minutes to an hour-plus education program? Not a shabby deal. They’ve got four series: Kids, America’s Stories, History and Natural Wonders. Go give it a look, this could be perfect for those of you with an iPod and a longer commute.
